SAUSAGE-STUFFING MACHINE.

EBPECIFICATION forming part of Letters Patent No. 316,352, dated April21, 1885.

Application M May 7,1ss4. (N0 model.)

.To all whom it may concern:

Be it known that 1, CHARLES FORSOHNER, of the city, county, and State ofNew York, bar e invented certain Improvements in Sausage StuffingMachines; and I do hereby declare that the followingis a full and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification-- Figure 1 being a front viewof theimproved machine; Fig. 2, a rear View of the same; Fig. 3, a top Viewthereof; Fig. 4, a vertical section ofaportion ofthe machine in a planeindicated by the line was, Figs. 2 and 8; Fig. 5, a vertical section ofa portion of the machine in a plane indicated by the line 0, Figs. 1 and2.

Like letters designate corresponding parts in all of the figures.

I have represented in the drawings a vertical machine to which myimprovements are applied; but they may be applied also to a horizontalmachine.

In the machine represented, A is the base on which the other parts ofthe machine are mounted; B B, standards, on the upper ends of which abearinghead, 0, is secured and supported, D, the sausage cylinder orreceptacle arranged under the head 0, and adapted to be drawn forward inways on the base A sufficiently to bring it out from under the head forfilling it with sausage-meat, and when returned to a position centrallyunder the head to be held there by a pin, a, passed down through itsbase-flange or bottom and into the base A of the machine; E, the piston;F, a vertical rack attached to the piston and gearing into a pinion, G;H, a worm-wheel on the shaft of the pinion I, a worm shaft gearing intothe worm-wheel, and J a handle, or its equivalent, for turning thewormshaft,to which it is attached, for forcing down the piston Ethroughthe medium of the said worm-shaft, worm-wheel, pinion, and rack.

In the parts above mentioned no novelty is herein claimed, except in theconstruction of the bearing-head G, pinion G, and its shaft mounted inthe said head, and in the rack F, mounted in relation to the said parts.

The improvement in the construction and arrangement of these parts is asfollows: The head 0 is cast in one solid piece, is slotted vertically toreceive the rack F, the smooth G and journals 0 c of its shaft, whichjournals are made as large in diameter as, or a little larger than, thepinion is in diameter around the extreme points of its leaves or cogs,as shown. By this construction all of these parts are made very cheaply,especially the bearing 0, requiring no parts to be added or removed, andthe whole construction is extremely strong and durable, never liable toget out of order, and the rack and pinion work very accurately togetherand without loose play.

Since the descent of thepiston E by the action of the worm-shaft I onthe worm-wheel H is slow and powerful for forcing down the sausagemeatin the cylinder, and since there is little power required in raising thepiston again out of the cylinder, so that a quick return motion isdesired to gain time,it is common to ungear the worm-shaft from theworm-wheel and to raise the piston by means of a handle, K, on the shaftof the worm-wheel and pinion. The ungearing of the worm-wheel andworm'shaft has been effected by simply reversing the mo tion of theshaft, which has an endwise motion in its bearings sufficient to effectthis ungearing, the worm-shaft turning back freely in the directiontoward its handle by the simple travel of its screw, while theworm-wheel, then stationary, acts as a nut thereto; and a forward motionof the worm-shaft, after ungearing, by a similar action again, bringsitinto gear with the worm-wheel, and then begins to act thereon forforcing down the piston again.

With this construction the more or less elastic resistance of thesausage-meat tends to force forward more of the meat at the outlet afterthe action of the worm-wheel ceases, and thus in putting on new skinsafter the previous ones are filled there is more or less of the meatforced out. This can be prevented by raising the piston a little withthe reversal of the worm-shaft; but with the ungearing device in use, asabove stated, the reversal of thejmo tion of the Worm-shaft simplyungears the worm from the worm-Wheel, and has no effect to raise thepiston; also,the weight of the piston E and its vertical driving-rack F,when IOO raised to the top of the cylinder D and-the latter is empty,will cause the worm-wheel to turn and ungear from the worm-shaft bydrivingit endwise, whenever the machine gets to working smoothly,which'in itself is desirable, and thus without some means of holding upthe piston and rack above the empty cylinder, they have to be held up byhand, or be subject to frequent otherwise unnecessary lifting. To avoidthese difliculties I form a circular groove, f, in the periphery of theworm-shaft in a proper position, and employ alatch, L, pivoted to theframe of the machine at g, with its end h over the worm-shaft heavierthan the other end, so as to drop and rest in the groove f of theworm-shaft when the latter is in gear with the worm-wheel, and therebyprevent ungearing the shaft from the worm-wheel, when it is desired toraise the piston by the reverse motion of the wormshaft, for theabove-named or any other purpose. WVhen, however, the worm-shaft is tobe purposely ungeared from the worm-wheel, the latch L is raised out ofthe groove f by simply pressing down on athumb-piece, t, on the otherend of thelatch, or by equivalent means, when the worm-shaft is free tobe ungeared by turning it backward. On turning it forward again thelatch drops into the groove f as soon as the worm-shaft is in gear withthe worm wheel. Any suitable construction of the latch L and equivalentof the groove f may be used.

I claim as my invention- 1. The combination of the solid bearing 0, therack F, and pinion G, the bearing being slotted to receive the rack, thepinion bearing journals 0 c as large in diameter as the pinion itself,and the bearing having an aperture of sufficient diameter to receive thepinion and its journals, for the purpose specified.

2. In combination with the piston E, driving-rack F, pinion G, andworm-wheel H of a sausage-stuffing machine, the worm-shaft I, providedwith a peripheral groove, f, and pivoted latch L, carrying athumb-piece, i, and weight k, arranged and operating substantially asand for the purpose herein specified.
